Title: Network system and image forming device
Inventor: YAJIMA MASAHIKO
IPC: B41J29/38
Filed: 1998-07-07
Abstract: PROBLEM TO BE SOLVED: To smoothly handle an error in a multi-address output while evading an increase in the communication traffic of a network. SOLUTION: A printer which is not ready for printing among printers determined as output destinations of a multi-address output receives only a data acquisition indication which is smaller in data amount than printing data from a server (S313) and stores it (S316). Then the printer when becoming ready for printing takes the data acquisition indication out of the memory (S319), obtains data acquisition destination information from the indication (S320), and acquires printing data from the data acquisition destination and saves the data (S308). Thus, while retransmission of the printing data to the printer which is not ready for printing from the server is avoided, the printer can acquire the printing data and starts printing after becoming ready for printing.

IPC: B62D25/02
Filed: 1999-07-06
Abstract: PROBLEM TO BE SOLVED: To partially increase the bending rigidity and a lateral compression rigidity of a hollow car body frame member by using a reinforcement member for a hollow car body frame member, fixed in an internal space of the hollow car body frame member in a state that it partially closes the inernal space. SOLUTION: Structural members 2, 3 are integrally connected to a hollow car body frame member 1 by spot welding. A reinforcement member 4 is mounted in an internal space defined by a U-shaped part of the structural member 3 having a flanged U-shaped cross section and the structural member 2. The peripheral outline of the reinforcement member 4 is approximately agreed with the shape of the internal space. The reinforcement member 4 has the shape of rectangular parallelopiped, and is formed by a honeycomb structure consisting of small chambers opened at its one end, closed at the other end, and having a square cross section. A hook-shaped projection is formed on an outer surface of a bottom wall of the reinforcement member 4. The hook-shaped projection fixes the reinforcement member 4 inside of the hollow car body frame member 1. Whereby the bending rigidity and the lateral compression rigidity of the hollow car body frame member can be effectively increased while minimizing the increase of a weight of a car body.

Title: Combustion device
Inventor: HIRATA YASUSHI
IPC: F23N5/10
Filed: 1986-08-18
Abstract: PURPOSE:To restrict the amount of production of NOx and maintain stably combustion condition from a high combustion to a low combustion, by a method wherein the supplying amount of a fuel supply means or an air supplying means is controlled so that the output signal of a temperature detecting unit becomes a given value in an area, in which the output signal of a flame electric current detecting unit becomes larger than a set value. CONSTITUTION:A flame rod 13 transmits an ion current If, flowing through the combustion flame 12 of a burner 1, to the flame electric current detecting nit 15 of a control circuit 14. An electromotive force, generated in the temperature measuring contact 18 of a thermocouple 17, provided in a flow regulating space 3, is transmitted to the temperature detecting unit 20 of the control circuit 14, while a temperature retrieving unit 21 outputs a signal for changing the amount of combustion to an air ratio control unit 22 so that the output signal of the temperature detecting unit 20 becomes a given value. The flow regulating space 3 receives radiant heat from a combustion wire net 4 and the flame 12 of the surface thereof directly, therefore, the output signal from the thermocouple 17 shows a high peak value in the ratio of combustion air to fuel or the air ratio lambda=1.0. Accordingly, the air ratio control unit 22 increases or decreases the supplying amount of fuel of the pump 6 so that the electromotive force Ev becomes a proper value or Ev=(a), for example, whereby the air ratio may be controlled so as to be in the vicinity of lambda=1.5.

Abstract: PROBLEM TO BE SOLVED: To make it possible to end a film at the end parts of a substrate, at the time of forming the film on the surface of the board, by providing a contact preventing part for preventing a part from coming in touch with the end parts of the substrate. SOLUTION: A contact preventing part 214 is provided in the boundary part between a substrate mount part 211 and a substrate guiding part 212. This contact preventing part 214 prevents a part from coming into contact with the end parts of a substrate 22 by a groove (a) formed along the periphery of the substrate 22 put on a substrate mount part 211. The outside diameter of the groove (a) is set so as to be a size larger than that of the substrate 22, and its inside diameter is set so as to be a size smaller. Consequently, the end parts of the substrate 22 put on the substrate mount part 211 protrude from the substrate mount part 211, and do not touch a substrate mount table 21. So, a film 23 to be formed on the surface of the substrate 22 and a film 23 to be formed on the surfaces of the substrate guiding part 212 and a radiating part 213 are not formed as a continuous film.  Namely, the film 23 formed on the surface of the substrate 22 ends at their end parts.

Filed: 1981-12-02
Abstract: PURPOSE:To reduce the dimensions of an autotransformer with a phase-shifting winding relatively and to unify the specifications of said transformer and additional transformers for rectifiers so as to simplify the specifications, by installing the autotransformer with the phase-shifting winding on the power source side, by installing the transformers for rectifiers in series to said transformer, and by dispensing thereby with tap windings and phase-shifting windings which are attached usually to said transformer. CONSTITUTION:In the figure, a transformer 2 has an input connection, and phase-shifting windings 3a, 3a', 3b, 3b' and 3c, 3c' for taking out voltages in the  phases of 0 degree + alpha degree, and of 0 degree - alpha degree are arranged on  an iron core of each phase, while taps 4a, 4b and 4c are provided on a serial  winding. When a supply voltage changes in this constitution, a voltage having a constant phase angle can be supplied stably to each transformer on the secondary side by varying the taps fitted to the serial winding without providing each  phase-shifting winding with a tap as is the case in a conventional transformer  with phase-shifting winding for a rectifier, since a voltage per one turn (volt/ turn) is always constant.
